<div></div>
<div>&nbsp; &nbsp;&quot;什么程度？&quot;</div>
<div></div>
<div>&nbsp; &nbsp;&quot;像喜欢春天的熊一样。&quot;</div>
<div></div>
<div>&nbsp; &nbsp;&quot;春天的熊？&quot;绿子再次扬起脸，&quot;什么春天的熊？&quot;</div>
<div>&nbsp; &nbsp;&quot;春天的原野里，你一个人正走着，对面走来一只可爱的小熊，浑身的毛活像天鹅绒，眼睛圆鼓鼓的。它对你说道</div>
<div>&nbsp; &nbsp;：&quot;你好，小姐，和我一块儿打滚玩好吗？&quot;接着，你就和小熊抱在一起，顺着长满三叶草的山坡&quot;咕噜咕噜&quot;滚下去</div>
<div>&nbsp; &nbsp;，玩了整整一天。你说棒不棒？&quot;</div>
<div></div>
<div>&nbsp; &nbsp;&quot;太棒了。&quot;</div>
<div></div>
<div>&nbsp; &nbsp;&quot;我就这么喜欢你。&quot;</div>
<div></div>
<div></div>
<div>挪威的森林是一片不曾存在的森林。</div>
<div>那个森林很大，里面什么植物都有。</div>
<div>渡边在其中发现了一颗渐渐生长出来的--仙人掌。是的，它会慢慢长出点和环。</div>
<div>渡边很好奇它的最长简单路径长度。</div>
